These default CROSS_COMPILE settings allow us to test target architectures with: $ cd /path/to/tools/testing/selftests/nolibc/ $ for arch in powerpc powerpc64 powerpc64le; do \ make run-user XARCH=$arch | grep "status: "; \ done If want to use another cross compiler, please simply pass CROSS_COMPILE or CC as before.
